DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a method according to the preamble of attached claim 1 and an arrangement according to the preamble of attached claim 3 for televoting in an intelligent network.
2. Description of Related Art
Fast developments in telecommunications have enabled operators to provide various services for users. Network architecture offering advanced services is called an intelligent network, generally abbreviated IN. IN architecture can be applied to most telecommunication networks, such as Public Switched Telephone Networks PSTN, mobile communication networks, Packet Switched Public Data Networks PSPDN, Integrated Services Digital Networks ISDN and Broadband Integrated Services Digital Networks B-ISDN. Irrespective of the network technology, the object of the intelligent network architecture is to facilitate design, control and management of new teleservices. With regard to present IN specifications, reference is made to Advanced Intelligent Network, Release 1 (AIN Rel.1) by Bellcore and Capability Set 1 (CS-1) by CCITT.
The IN architecture is illustrated by FIG. 1, in which physical entities are presented as rectangles or circles and functional entities as ovals. Signalling connections are indicated by dotted lines, and actual transport, which is e.g. speech, by solid lines. Optional functional entities are indicated by a dotted line. The signalling network shown in the figure is a network according to Signalling System No. 7 (SS7, a known signalling system described in the blue book Specifications of Signalling System No. 7, Melbourne 1988 of CCITT (now: ITU-T)).
We shall first describe the architecture of the IN physical level. Subscriber equipment SE, such as a telephone, computer or telefax, is switched either directly to a Service Switching Point SSP or to a Network Access Point NAP.
The service switching point SSP offers the user access to the network and takes care of all the necessary selection activities. The SSP is also able to detect any requests for service in the intelligent network. Operatively, the SSP contains call management and service selection functions.
The network access point NAP is a conventional exchange that contains a Call Control Function CCF and is able to differentiate between conventional calls and calls needing the services provided by the intelligent network and to route the latter to the appropriate SSP, the exchange being e.g. a DX 220 exchange by the applicant.
The Service Control Point SCP contains the service logic programs used for providing intelligent network services.
The Service Data Point SDP is a database containing data on the customer and network, the data being used by the service logic programs of the SCP to provide individualized services. The SCP can use the services of the SDP either directly or through a signalling network.
An Intelligent Peripheral IP provides special-purpose functions, such as notifications and voice and multiple choice detection.
A Service Switching and Control Point SSCP comprises an SCP and an SSP in a single node (i.e. if an SSP node shown in the figure comprises both SCF and SDF entities, it is an SSCP).
The functions of a Service Management Point SMP comprise management of the database (SDP), control and testing of the network, and collection of network information. It can be connected to all other physical entities.
A Service Creation Environment Point SCEP is used for defining, developing and testing the IN services, and for supplying the services to the SMP.
An Adjunct AD corresponds operationally to the service control point SCP but is connected directly to an SSP by a high-speed data link (e.g. ISDN 30B+D connection) and not through a common channel signalling network SS No. 7.
A Service Node SN can control IN services and transfer data to and from the users. It communicates directly with one or more SSPs.
A Service Management Access Point SMAP is a physical entity that provides certain users with a connection to the SMP.
